I'm not sure specifically which 'che graphic novel' you're referring to. There could be many graphic novels with various themes. It might be about a fictional adventure, a historical event, or a personal story.
Since I don't know the exact 'che graphic novel', it's difficult to say precisely. However, generally, a graphic novel can cover a wide range of topics. It could be a coming - of - age story, where the main character faces challenges and grows throughout the narrative. Or it could be a science - fiction tale set in a far - off future with strange new worlds and technologies.
